To all whomit may concern:

Be it known that I, LEWIS A. Comnmx, a citizen of the United States, residing at Norfolk, in the county of Norfolk and State of Virginia, have invented new and useful Improvements in Waterproofing Composition, of which the following is a specification.

Thisinvention relates to a new and improved waterproofing filler composition especially. prepared for-application to concrete and masonry walls or structures, the purpose being to render the walls or structures to which the composition .is applied, proof against the entrance of water or moisture. The composition is also adapted for use in connection with wooden structures, es ecially those buried. in the ground, or su merged under water, such as columns, telegraph-poles, fence-posts and piles, although the method .of' applying the compo sition to concrete and masonry structures differs somewhat from-the method employed when applying the same to wooden structures. In the'former, the composition is applied by means of an ordinary paintbrush, whereas in the latter case the composition isapplied by submerging or immersing the structures therein.

The object of the Invention is to provide a comparatively inexpensive \vate'rprooting .fillcr composition in free flowing liquid form, that may be readily compounded and easily applied, and the chief characteristics of which is, that when applied, to the surface to be rendered water ormoisture-proof, it will penetrate, for a considerable depth, the said surface, effectually entering and closing all the crevices or interstices thereof.

Other characteristics of the composition are, that it is practically colorless, and will not therefore, discolor or alter the general appearance of the surface. to which it is applied; and is absolutely without glaze or gloss, which is a desidcratum of no small-iniportance. in compositions of this character..

In order to enable others to understand, prepare and apply m'y improi ed composi tion, I will now proceed. to describe the same in detail, giving what I have discovered to be the proper proportions forone gallon of the mixture, it; bein understood of course that larger or smaller quantities are to be prepared in like proportions.

The formula is as follows: One pint of gum rubber cement (a solution of gum rubher and gasolene), One-half pint spirits of turpentine. Six and one-half pints of gasolene. J j

The three ingredients above named and in the proportions stated, are thoroughly wise until the particles are fully broken up, the resulting mixture consisting of innumerable globules of the gum-rubber cement and turpentine, the whole being in suspension in the gasolene which latter acts asa vehicle.

It has been found in actual practice, that when'the'fluid filler is applied to a wall surface, as by a brush, the small globules that are held in suspension in the gasolene will readily and quickly enter or penetrate, the crevices or interstices of the wall and effectually close the same, rendering, not. only the surface of the wall water and moisture proof, but the wall structure itself is rendered waterproof to a considerable depth.

Ordinarily one or two coats of the composition are amply suflicient to render a concrete or brick wall absolutely waterproof and as the composition is practically colorless and has no gloss or glaze producing properties, the general appearance of the surface will not be altered in the least.

\Vhen it is desired to waterproof wooden posts, columns, or other timbers, these are submerged or immersed in the composition and allowed to remain. therein for-a suflicient length of time to enable the same to 'enter and till the pores thereof, the length of time depending somewhat upon the character and grain of the timber.

Itwill be understood that my improved waterproof composition is not a paint but a filler and differs from a paint in that the latter when applied to a wall or surface simply gives a coating thereto, whereas my improved filler penetrates to a considerable distance the wall or structure to which it is applied, effectually closing the pores, crevices or interstices making the surface absolutely water or moisture proof, the sur face of the wall or structure to which the composition is applied not being otherwise affected in the slightest degree.

VV-hat I claim is,-

1. A free flowing liquid waterproofing .mixed either by agitation, stirring or otherfiller, comprising a mixture of gum rubber cement, spirits of turpentine and gasolene, in substantially the" following proportions- 12% parts gum rubber cement, 6;]; parts 5 spirits of turpentine, and 81:} arts gasolene.

2. The herein described iiquid waterproofing 'filler composition, comprising a mixture of 12% parts of gumrubbe'r cement, Gi'parts spirits of turpentine, and 81% parts 10 gasolene, the physical characteristics of which are a free flowing practically colorless In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
